Hi Jakub, David, We repro the issue on the server side using this client command: $ wrk -b2.2.2.2 -t4 -c1000 -d5 --timeout 5s https://2.2.2.3:20443/256000b.img Port 20443 is configured with: ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256; sendfile off; Important: 1. Couldn't repro with files smaller than 40KB. 2. Couldn't repro with "sendfile on;" In addition, we collected the vmcore (forced by panic_on_warn), it can be downloaded from here: https://drive.google.com/file/d/1Fi2dzgq6k2hb2L_kwyntRjfLF6_RmbxB/view?usp=sharing Regards, Tariq
